Instruments
and ensemblesStarting from the Pegu period,
most musical instruments were classified from their resounding
material, thus the "kye" (brass - cymbals, bells and gongs), the "kyo"
(string - harp, violin and zither), the "tha-ye" (leather -drums), the
"lay" (wind - flutes, trumpets and oboe) and the "let-khok" (wooden -
clappers) instruments.
As it makes more sense to distinguish between their use in performance,
it seems to be more practical to divide these instruments whether
they are used for ensemble or chamber music:

(Without
pictures and descriptions: The main drums "pa ma" and "sakhum" (on a
frame), both part of the "hcau laun pa" drum ensembles, where the
biggest drum is always positioned on the left side - as well as
several flutes, violins and the almost forgotten "Don Minn"
zither.)
